Biomass blending as a way to reduce NOx emissions

The use of biomass as a source of energy through combustion has been subject to growing interest, notably to tackle the issue of climate change. This has caused an increasing demand on woody biomass resources, and led to consider other biomass resources, such as agricultural residues. Among the atmospheric pollutants emitted during biomass combustion are nitrogen oxides (NOx: NO and NO2

Commercialisation options for biomass energy

A number of rice husk briquetting plants established in Nepal in the late 1980s were later closed because of low profitability, one main reason being an increase in the local cost of husk. Long-term supply contracts with the residue generators (i.e. rice and saw-mills) may be a satisfactory approach to avoid this type of risk in such cases.
